A track bicycle or track bike is a form of fixed-gear bicycle optimized for racing at a velodrome or at an outdoor track. Some road racing and club cyclists use a fixed-gear bicycle for training during the winter months, generally using a relatively low gear ratio, believed to help develop a good pedalling style. [5]
Bicycle chains used in track, fixed gear and single speed cycling come in two common roller widths (the internal width between the inner plates), which is either 2.38 mm (3 ⁄ 32 in) or 3.18 mm (1 ⁄ 8 in). The chainring, sprocket and chain should all be the same width.
They have a single gear ratio, a fixed drivetrain (i.e. no freewheel), no brakes, and are minimally adorned with other components that would otherwise be typical for a racing bicycle. BMX bikes are designed for stunts, tricks, and racing on dirt BMX tracks. They have a single gear ratio with a freewheel and are built with smaller frames and ...
One standard option for the Brompton folding bicycle is to use a 3-speed hub gear (roughly a 30% difference between gear ratios) in combination with a 2-speed derailleur gear (roughly a 15% difference) to give 6 distinct gear ratios; this is an example of half-step gearing. Some Brompton suppliers offer a 2-speed chainring 'Mountain Drive' as ...
In a fixed-gear bicycle, the bottom bracket should be high enough to prevent the pedals from coming in contact with the ground while cornering but is not always achieved. A lower bottom bracket creates a lower center of gravity and allows for a larger frame without creating an uncomfortable standover height.
A fixed gear frame, with a cream color known as "Kustard" and the signature color of the mark, with 120mm rear dropout spacing. The G typified the eclectic nature of Koswell frames: steel frame and fork, with lugged joints, but a TIG-welded bottom bracket and threadless fork, melding both traditional styles (see Rivendell ) and contemporary ...
Wondering what the stars have in store for you this month? A professional astrologer shares her January 2025 horoscope predictions for every zodiac sign.
A great "on road" gear ratio, for the 26″ wheel, is 42:17, approximately a 2.5:1 ratio and 64.2 gear inches for versatile tour riding. Many British enthusiasts used to tour on 27–inch–wheeled lightweights on a single fixed–gear of 69 inches before multi–speed gearing became universally popular, though this certainly made for tough ...
